EGR Cooler Repair & Service in Hyderabad
Specialist service for exhaust gas recirculation coolers
The EGR cooler reduces exhaust gas temperature before recirculation into the engine, improving emissions and engine efficiency. However, EGR coolers are prone to internal blockage from carbon accumulation and can develop coolant leaks that cause serious engine problems. At Metre Per Second, we provide complete EGR cooler services including diagnosis, cleaning, repair, and replacement. Our experience includes all types of EGR coolers from simple single-pass designs to complex multi-pass coolers used in modern diesel engines. We understand the critical importance of proper EGR cooler function for engine health and can advise on the best approach - whether cleaning, repair, or replacement - based on your cooler's condition.
Common EGR System Problems We Fix
EGR Cooler Blockage
Carbon deposits restrict exhaust flow through cooler
Symptoms:

External Leak
Gaskets or connections leak coolant externally
Symptoms:
- Coolant leak visible
